Gastroscopy (stomach endoscopy)

A gastroscopy should be performed if there is unexplained upper abdominal pain, heartburn, difficulty swallowing, or weight loss. The examination makes it possible to evaluate the lining of the esophagus, stomach and duodenum, typically lasts a few minutes, and is painless.

Tumors, ulcers, and inflammation can be detected early, and tissue sampling or minor procedures (such as hemostasis and polypectomy) can be performed.

Before the procedure: The patient must be emtpy-stomached, and should avoid smoking.

During the procedure: The patient lies on his/her left side, and the scope is passed into the mouth. The patient is given a plastic bite ring to protect the scope. Breathing is unaffected. The patient may also choose to receive a sedative.

If a sedative is provided, the patient is legally required to NOT drive a vehicle NOR ride a bicycle after the procedure.
